Answer:
(X+5)(x^2-5x+25)
Step-by-step explanation:
120 is your answer cause half 120 is 60
Answer:
x=28
Step-by-step explanation:
So a triangle is 180 degrees in total then you would subtract 40 from 180 because the top angle and leaving you with 140 then divide by 5 because the bottom two getting you 28 then you could just plug in 28 for x on each angle
180-40=140
140/5=28
2(28)=56
56 is angle A
Total divided by number of rows=number per row
63/7=9
9 per row
